BAGWORM MOTHS OF THE WESTERN HEMISPHERE 157 



Discussion.— This unique specimen structurally is very different 

 from any known species. It is possible, though unlikely, that the 

 specimen may represent an unusual variation of 0. kirbyi. Another 

 possibility is that this is the larval bag of one of the largest New 

 World psycliids, 0. specter. The case of 0. kirbyi, as now Iviiown, is 

 relatively distinct, consisting of a cross-thatching of twigs covered by 

 a thin but firm layer of silk, and the larval bag of 0. specter is unknown 

 at present. 



Material examined.^ — 1 case: 



"W. Cordillera, de los Cruces," case (9), 2200 meters, collected by A. H. 

 Fassl, BM. 



Case No, 3 

 Oiketiciis species 



Figures 139, 140 



Case. — (Figs. 139, 140.) Length 60-80 mm.; greatest diameter 

 15-20 mm. More or less spindle-shaped in outline; exterior of case 

 largely naked except for sparse scattering of dried mosslike vegetation, 

 small thorns concentrated toward posterior end. Texture of case un- 

 usually thin, parchment-like. Color, light grey to dark fuscous. 



Recorded hosts. — "on barberry bushes." 



Discussion. — This series of larval cases evidently represents an 

 undescribed species, probably belonging to the genus Oiketicus. 



Material examined. — 20 cases: 



Chile: Puerto Eugenia, north side of Navarino Island, 20 cases, collected by 

 Junius Bird, USNM. 



Case No. 4 



Oiketicus species 



Figure 141 



Case. — (Fig. 141.) Mature cases 60-70 mm. length, greatest 

 width usually 10-13 mm. Outline of case slender fusiform, with either 

 few, closely appressed, interwoven fragments of leaves, or more leafy, 

 attached leaves widely diverging. Color in general rather dark, very 

 few to almost no twigs incorporated into structure. Overlying 

 sheath of silk absent. 



Recorded hosts. — "an Mandelbaum." 



Discussion. — Several larval bags have been collected in Havana, 

 Cuba, by W. H. Hoffmann. All of them undoubtedly belong to the 

 same species, but they have not been associated definitely with any 

 known species. The cases lack a heavy thatching of twigs and are 

 without any whitish silk covering on the exterior, and thus they 

 appear more similar to the known cases of 0. abbotii and 0. toiimeyi
